<a name="index-objfiles-in-guile"></a>
<a name="index-_003cgdb_003aobjfile_003e"></a>
<p><small>GDB</small> loads symbols for an inferior from various
symbol-containing files (see <a href="Files.html#Files">Files</a>).  These include the primary
executable file, any shared libraries used by the inferior, and any
separate debug info files (see <a href="Separate-Debug-Files.html#Separate-Debug-Files">Separate Debug Files</a>).
<small>GDB</small> calls these symbol-containing files <em>objfiles</em>.
</p>
<p>Each objfile is represented as an object of type <code>&lt;gdb:objfile&gt;</code>.
</p>
<p>The following objfile-related procedures are provided by the
<code>(gdb)</code> module:
</p>
<dl>
<dt><a name="index-objfile_003f"></a>Scheme Procedure: <strong>objfile?</strong> <em>object</em></dt>
<dd><p>Return <code>#t</code> if <var>object</var> is a <code>&lt;gdb:objfile&gt;</code> object.
Otherwise return <code>#f</code>.
</p></dd></dl>

<dl>
<dt><a name="index-objfile_002dvalid_003f"></a>Scheme Procedure: <strong>objfile-valid?</strong> <em>objfile</em></dt>
<dd><p>Return <code>#t</code> if <var>objfile</var> is valid, <code>#f</code> if not.
A <code>&lt;gdb:objfile&gt;</code> object can become invalid
if the object file it refers to is not loaded in <small>GDB</small> any
longer.  All other <code>&lt;gdb:objfile&gt;</code> procedures will throw an exception
if it is invalid at the time the procedure is called.
</p></dd></dl>

<dl>
<dt><a name="index-objfile_002dfilename"></a>Scheme Procedure: <strong>objfile-filename</strong> <em>objfile</em></dt>
<dd><p>Return the file name of <var>objfile</var> as a string,
with symbolic links resolved.
</p></dd></dl>

<dl>
<dt><a name="index-objfile_002dprogspace"></a>Scheme Procedure: <strong>objfile-progspace</strong> <em>objfile</em></dt>
<dd><p>Return the <code>&lt;gdb:progspace&gt;</code> that this object file lives in.
See <a href="Progspaces-In-Guile.html#Progspaces-In-Guile">Progspaces In Guile</a>, for more on progspaces.
</p></dd></dl>

<dl>
<dt><a name="index-objfile_002dpretty_002dprinters"></a>Scheme Procedure: <strong>objfile-pretty-printers</strong> <em>objfile</em></dt>
<dd><p>Return the list of registered <code>&lt;gdb:pretty-printer&gt;</code> objects for
<var>objfile</var>.  See <a href="Guile-Pretty-Printing-API.html#Guile-Pretty-Printing-API">Guile Pretty Printing API</a>, for more information.
</p></dd></dl>

<dl>
<dt><a name="index-set_002dobjfile_002dpretty_002dprinters_0021"></a>Scheme Procedure: <strong>set-objfile-pretty-printers!</strong> <em>objfile printer-list</em></dt>
<dd><p>Set the list of registered <code>&lt;gdb:pretty-printer&gt;</code> objects for
<var>objfile</var> to <var>printer-list</var>.  The
<var>printer-list</var> must be a list of <code>&lt;gdb:pretty-printer&gt;</code> objects.
See <a href="Guile-Pretty-Printing-API.html#Guile-Pretty-Printing-API">Guile Pretty Printing API</a>, for more information.
</p></dd></dl>

<dl>
<dt><a name="index-current_002dobjfile"></a>Scheme Procedure: <strong>current-objfile</strong></dt>
<dd><p>When auto-loading a Guile script (see <a href="Guile-Auto_002dloading.html#Guile-Auto_002dloading">Guile Auto-loading</a>), <small>GDB</small>
sets the &ldquo;current objfile&rdquo; to the corresponding objfile.  This
function returns the current objfile.  If there is no current objfile,
this function returns <code>#f</code>.
</p></dd></dl>

<dl>
<dt><a name="index-objfiles"></a>Scheme Procedure: <strong>objfiles</strong></dt>
<dd><p>Return a list of all the objfiles in the current program space.
</p></dd></dl>
